And here's the PCB of the 512GB model. This 6Gbps storage unit makes use of 25nm MLC synchronous NAND, its actually very similar to what a Vertex 3 uses. It has a good sixteen NAND ICs with four 8GB die per package.
To the right you can see one of the two DRAM chips cache split into two 256MB chips, thus equaling to 512MB. As stated both 6Gbps and 3Gbps connections can be used albeit 6Gbps is the way to go.
And there it is, the Everest 2 controller. The Everest is OCZ Indilinx's 2nd 6Gbps controller the first SSDs series using it thus is the OCZ Vertex 4 series SSD. And for those that wonder, the Octane has a IDX300 series controller.
We see sixteen 32GB Intel NAND modules and another module of Micron 256MB DRAM. This gives us a RAW NAND Flash capacity of 512GB and a DRAM cache of 512MB.
In this article we test, benchmark and review the all new OCZ Vertex 450 SSD. Armed with the new Indilinx Barefoot 3 controller this is the fifth incarnation of the popular OCZ Vertex series. Will it be as fast and competitive as it's predecessors ? Well let's see and find out shall we ?
OCZ Vertex 3.20 SSD review
In this article we test, benchmark and review the OCZ Vertex 3.20 SSD. What a great and fast piece of technology this is. An 20nm NAND flash SSD that is speedy and actually amongst the the rest of the devices tested, but also mroe affordable. Head on over into the review.
OCZ Vertex 4 SSD review with 1.5 firmware
We retest the OCZ Vertex 4 SSD yet now with 1.5 firmware update. , again bringing more performance towards the Vertex 4 series of SSDs. And albeit the difference is not as big as the 1.4 release was, it certainly makes a difference as this article will show you.
OCZ Vertex 4 SSD revisited with FW 1.4RC review
We revisit the OCZ Vertex 4 256 and 512GB SSD review, this time with Firmware 1.4 which makes the drives much faster. Armed with a new Indilinx Everest 2 controller this SSD is advertised as one of the fastest on the block with screaming IOPs performance. Lets have a look shall we ?
